Folk here may not be familiar with MySQL, so might not know the exact syntax - that wastes your time, and theirs of course ...
If Microsoft SQL Server is not involved at all (e.g. you are not transferring data between MySQL and MS SQL) you would probably be better off asking the question on a MySQL forum.
If MS SQL is involved then hopefully!! you'll get some good advice here
